Ten Syrian civilians were reportedly killed by rocket fire along the Jordanian-Syrian border on Saturday as heavy regime shelling threatened the lives of hundreds of refugees awaiting to cross into Jordan.

Syrian rebels claim that the incident increased to 180 the total number of refugees who have lost their lives in Damascus’ two-month aerial offensive.

“Two separate families were hit by a missile while trying to reach the Jordanian border, and 10 people died instantly,” claimed Mohammad Al Jayousi, a Syrian activist with the Local Coordination Committees based on the outskirts of Yadoudeh, the border town where the incident took place.

An estimated 30,000 displaced Syrians have been prevented by border clashes from fleeing to Jordan and reportedly remain stranded across the border region.

But around 1,000 refugees managed to cross into Jordan over the weekend, with 600 entering on Friday and 400 on Saturday, the Jordan Armed Forces said.
